![]() Webcasting live video with Flash Media Live Encoder. For the world of Flash video, the year 2. Adobe released Flash Media Live Encoder. Adding Flash Media Live Encoder to Adobe's product line makes Flash video web broadcasts of live events even easier and of the highest supported quality. Best of all, Flash Media Live Encoder is free to Flash Media Server licensees or users with Flash Video Streaming Service accounts. This article provides a quick overview of how to set up a live webcast using Flash Media Live Encoder and Flash Media Server. Overview of Flash Media Live Encoder. ![]() Since its inception, Flash Media Server has supported live video and audio streaming. Now adding Flash Media Live Encoder for encoding live web broadcasts offers two important benefits: the highest quality video supported, and quicker, easier deployment. Flash Media Live Encoder directly delivers the highest quality supported video by using On. VP6 encoding. Previously, this was only possible through the use of third- party solutions. Flash Media Live Encoder provides quicker, easier deployment by being a fully featured acquisition and encoding application that natively integrates with Flash Media Server. Previously, the acquisition and encoding functionality had to be custom- coded using the Flash authoring tool. This article provides a basic overview of using Flash Media Server, Flash Media Live Encoder, and either Flash CS3 Professional or Dreamweaver CS3 to create a live web broadcasting application. Figure 1 presents each of these in context with the other elements of a basic live broadcast. Figure 1. Live web broadcast using Flash Media Live Encoder. The elements of the basic live broadcast illustrated in Figure 1 are as follows: Live event: The subject to be broadcast—business, educational, or political speakers, performers, sporting events, or any other event. Audio/video capture: Cameras and/or microphones connected to the computer running Flash Media Live Encoder. Onsite encoding: Encoding provided using Flash Media Live Encoder on a computer with a reliable Internet connection. Internet: Liaison between computers running Flash Media Server, Flash Media Live Encoder, a web server hosting the playback SWF file, and the audience's computers. Flash Media Server or Flash Video Streaming Service servers: Flash Media Server (FMS) provides delivery of the video and audio streams using load balancing, failover, redundancy, and clustering via an origin/edge architecture. The Flash Video Streaming Service (FVSS) is provided through leading content delivery network (CDN) providers. FVSS provides an alternative to owning and operating your own FMS servers. Web server: Simple HTTP server hosting the Flash SWF file that is downloaded by the audience's computers to receive the webcast event. Only a single playback SWF file is required. Audience: Internet- connected event audience viewing the event using Flash Player to play the playback SWF file. The following sections step you through configuring Flash Media Server using Flash Media Live Encoder, and creating a playback SWF file. Configuring Flash Media Server. Flash Media Server offers a unique combination of traditional scalable streaming media capabilities and a flexible development environment for creating and delivering innovative, interactive media applications to the broadest possible audience. This article focuses solely on Flash Media Server's live streaming capabilities. This article assumes that you have Flash Media Server installed and running locally. The application setup is the same whether the server is running locally or remotely. You can use any version of Flash Media Server for this task, including the free Developer Edition. If you do not already have Flash Media Server installed, download it and follow the documentation to install it. To see a video tutorial covering the installation of Flash Media Server 2 on Windows as well as Linux, check out Train Simple videos: Introduction to Flash Media Server 2 in the Flash Media Server Developer Center. To create a Flash Media Server application for your live video stream, do the following: Go to the directory [Flash Media Server install directory]\Applications. In the Applications directory, make a subdirectory called my. Live. App. Note: Make sure that there are no typos in your subdirectory name. Hereafter, this subdirectory name is your Flash Media Server application name, and it will be referred to both in configuring the Flash Media Live Encoder and in authoring your playback SWF file. The spelling in each case must match exactly. Copy main. asc into the \Applications\my. Live. App directory. A version of main. Dreamweaver CS3. For Flash CS3 Professional users, extract the main. Samples. zip file linked to at the beginning of this article. For Dreamweaver users, the required main. Dreamweaver directory: [drive]: \Program Files\Adobe\Adobe Dreamweaver CS3\configuration\Templates\Video_Player. If you are still using Flash Professional 8, you can find the required main. Program Files\Macromedia\Flash 8\Samples and Tutorials\Samples\Components\FLVPlayback. Note: These versions of main. SWF file in a later section. In Flash Media Server, files with . Action. Script logic. Whichever version of main. Look for theapplication. Connect function. ![]() You may find the line p_client. Access, which prevents live streaming from happening by default. If you see it, be sure to comment out this line as follows: application. Connect = function(p_client, p_auto. Sense. BW). //Add security here. Access = ""; // prevents creating shared object or live streams. Connection(p_client). Sense. BW). this. Client. Bw(p_client). BWDone"). }That's all the setup required of you on the server side. Before proceeding to the next section, make sure that Flash Media Server is running. Using Flash Media Live Encoder. Flash Media Live Encoder is designed to enable live event producers to capture audio and video and stream it live to Flash Media Server or the FVSS. The intuitive user interface of Flash Media Live Encoder works seamlessly with plug- and- play cameras and microphones, and compatible analog- to- digital converters. Flash Media Live Encoder produces live Flash video with On. VP6 encoding, delivering high- quality footage with size and bit rate flexibility. You also get full audio control with the bit- rate efficient Nellymoser audio codec. Flash Media Live Encoder installs just like a regular desktop application. Currently Flash Media Live Encoder is available only for Windows XP. To make sure that your computer can run Flash Media Live Encoder, review the system requirements. Understanding the Flash Media Live Encoder interface. To help you get oriented to the Flash Media Live Encoder interface, Figure 2 highlights the Flash Media Live Encoder's main sections. Figure 2. Overview of the Flash Media Live Encoder interface. Following is a key with descriptions for the numbered sections in Figure 2: Menus. Preview displays: input (left) and output (right)Control panel: preset selector, video encoding settings, audio encoding settings, and output settings (not shown output metadata and encoding log)Control buttons: start and stop. Note: For a full description of all Flash Media Live Encoder's features, review the in- product help. You can access the help from the main menu by selecting Help > Flash Media Live Encoder Help. Sending your first live stream from Flash Media Live Encoder to Flash Media Server. To configure Flash Media Live Encoder to send your first live stream: Hook up a video source to the computer that Flash Media Live Encoder will be running on. Launch Flash Media Live Encoder. From the Preset Selector, select the setting for Medium Bandwidth (3. In the Video area, from the Device selector, ensure that the video source that you would like to use is both displayed and selected. Also ensure that the Video option is checked. In the Output area, set the following options to the values indicated (accepting the defaults on the other values should be fine): Stream to Flash Media Server: Selected. FMS URL: rtmp: //localhost/my. Live. App/instance. Make sure that there are no typos in your FMS URL. This URL is specifying the real- time messaging protocol, followed by host name (localhost), application name (my. Live. App), and creating an instance name (instance. In the next section, when you create playback SWF files, you will reference this URL and must match the spelling exactly.
